1) acetylandromedol
乙酰柽木醇毒
3) 4-hydroxy-2-butanone
乙酰乙醇
1.
4-hydroxy-2-butanone was prepared by condensation of acetone with formaldehyde over KF/Al_2O_3 instead of the aqueous NaOH solution,the shortcoming in the old method such as polymer yielding and the neutralization with weak acid was overcome.
用KF/Al2O3催化丙酮和甲醛缩合制备乙酰乙醇,并采用固定床反应方式,简化工艺过程,提高了生产效率,催化缩合收率高,选择性好,已工业化生产。
4) Eustigmata tamaricina
